S400 DEFINITION & SETTING QUESTION?

[SJATU]

Hi. . .

I'm getting acquainted with my new Canon S400 so many of my questions may seem basic.

What is the difference between compression and resolution in terms of picture quality?

When do you set compression at superfine, fine OR normal.

I understand the number of pixels. Why wouldn't I always want to set the largest number of pixels when I shoot? I don't always know whether I want to blow up a pix until I shoot it?

If I take a pix with the L(Large) 2272x1704 pixel size but only print a 5 X 7 or 3 X 5 print, will the quality of the print be better than if I shoot the picture M(Medium 1) 1600 x 1200 making the same size prints.

How does the compression address the quality/sharpness of the print?

Thanks.

Count on more exciting and stimulating questions later.

I always use superfine at largest size( But thats just me, and thats just so far)

I can't really answer the other stuff. I haven't done much printing because I don't have a photo printer yet.

Susan,

I am no authority on the subject so someone can correct me if I am wrong. But the lower settings are ok if you are really only doing web based pictures or email only. If you plan on printing go with the SF pics.
